Question

The material of solid cone is converted into the shape of solid cylinder of equal radius if the height of the cylinder is 5 cm what is the height of cone ?

Answer 1

Since the volumes are equal.

 1/3πr²h1 = πr²h2

 πr² cancel from both the side.

h1/3 = h2  

∵ h2 = 5

∵ h1 = 3h2

       = 3×5

      = 15 cm
